Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 76.8 Mbps. The complete list of 50 data speeds has a mean of x overbar=17.57 Mbps and a standard deviation of s=34.29 Mbps.
a. What is the difference between carrier's highest data speed and the mean of all 50 data speeds?
b. How many standard deviations is that [the difference found in part (a)]?
c. Convert the carrier's highest data speed to a z score.
d. If we consider data speeds that convert to z scores between -2 and 2 to be neither significantly low nor significantly high, is the carrier's highest data speed significant?
